Typical Applications
AD8338ACPZ-R7 is suitable for 6 applications: Ultrasound Imaging, Radar Systems, Communication Receivers, Industrial Instrumentation, Portable Electronics, Test and Measurement.
Ultrasound Imaging
The AD8338ACPZ-R7 is ideal for ultrasound systems where time-gain compensation (TGC) is required. Its 80 dB gain range and 18 MHz bandwidth allow precise amplification of weak echoes from deep tissue while attenuating strong near-field signals. The low power consumption of 3 mA is beneficial for portable ultrasound devices, and the differential signal path ensures high common-mode rejection, improving image quality.
Recommended
Radar Systems
In radar receivers, the AD8338ACPZ-R7 provides automatic gain control (AGC) to handle wide dynamic range of received signals. Its 18 MHz bandwidth supports intermediate frequency (IF) signals, and the 80 dB gain range allows adaptation to varying target distances. The low power consumption is advantageous for portable and battery-operated radar equipment, and the differential inputs reduce interference from common-mode noise.
Recommended
Communication Receivers
The AD8338ACPZ-R7 is used in communication receivers to adjust signal levels before demodulation. Its 18 MHz bandwidth covers typical IF frequencies, and the 80 dB gain range enables handling of signals from weak to strong. The low power consumption of 3 mA is ideal for battery-powered radios, and the differential output can directly drive ADCs, simplifying the signal chain.
Recommended
Industrial Instrumentation
In industrial instrumentation, the AD8338ACPZ-R7 provides programmable gain for sensor signal conditioning. Its wide gain range and low noise ensure accurate measurement of small signals from sensors like strain gauges and thermocouples. The 18 MHz bandwidth supports high-speed data acquisition, and the low power consumption is suitable for field instruments powered by batteries or energy harvesting.
Recommended
Portable Electronics
The AD8338ACPZ-R7 is well-suited for portable electronics due to its low power consumption of 3 mA and compact 3x3 mm LFCSP package. It can be used in handheld devices for signal conditioning, such as in portable ultrasound or spectrum analyzers. The wide gain range allows adaptation to varying input levels, and the differential signal path improves noise immunity in battery-powered designs.
Recommended
Test and Measurement
In test and measurement equipment, the AD8338ACPZ-R7 is used for gain control in signal generators and analyzers. Its 18 MHz bandwidth and 80 dB gain range allow precise amplitude control over a wide frequency range. The low power consumption is beneficial for benchtop instruments that require low heat dissipation, and the differential inputs/outputs facilitate balanced signal routing.

Key Differentiators
- Low power consumption of 3 mA (vs AD8330ACPZ-RL)
- Wide gain range of 80 dB (vs AD8330ACPZ-RL)
- Lower bandwidth of 18 MHz (vs AD8330ACPZ-RL)
Design Notes
The AD8338ACPZ-R7 operates from a single 5V supply and draws only 3 mA. Ensure a clean, low-impedance power source with adequate decoupling capacitors (e.g., 0.1 uF and 10 uF) placed close to the VPS pins to minimize noise and ripple.
For optimal performance, keep the differential input traces short and balanced to maintain common-mode rejection. Use a solid ground plane and avoid routing high-speed digital signals near the analog input pins. The exposed pad on the LFCSP package should be soldered to the ground plane for thermal and electrical stability.
Do not exceed the absolute maximum supply voltage of 5.5V. The gain control input should be driven from a low-impedance source to avoid gain errors. Also, ensure the input common-mode voltage is within the specified range to prevent distortion.
